4、 of Recommendations. ITU-T RECOMMENDATION 2.360 GRAPHIC GDMO: A GRAPHIC NOTATION FOR THE GUIDELINES FOR THE DEFINITION OF MANAGED OBJECTS Summary This Recommendation prescribes a graphic notation to provide an overview of GDMO/GRM specifications. GDMO, Guidelines for the Definition of Managed Object
5、s, is a formalism defined in Recommendation X.722 to define managed objects in Telecommunications Management Network (TMN). Attributes for representing relationships are defined in Recommendation X.732. The GDMO formalism is extended with a general relationship notation in Recommendation X.725 (Gene
6、ral Relationship Model). The overall object structure is defined by GDMO/GRM, while the syntax of the data is defined using Abstract Syntax Notation One (ASN.l), Recommendations X.208 or X.680. The three languages are widely used by many ITU Study Groups for the specification of managed objects for
7、many application areas. The languages are purely alphanumeric and the alphanumeric specifications using GDMOIGWASN. 1 are hard to overview. Current Recommendations using GDMO/GRM use various kinds of informal illustrations to provide overviews of different aspects of the specifications. However, the
8、y frequently use the same symbol for different notions, different symbols for the same notion, and can sometimes be misleading as to the contents of the specifications. Therefore, a standardized graphic notation was felt needed. The graphic notation shall be true to the notions of the alphanumeric n
9、otations. This Recommendation is based on: 0 an approved Requirement document, found in Appendix II; evaluation of some existing graphic notations, which did not meet the requirements; trial use on several Recommendations and other application areas. Source ITU-T Recommendation 2.360 was prepared by
10、 ITU-T Study Group 10 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 6th of May 1997.

11、ECMN Z-3bO-ENGL 1997 48b257L Ob41735 522 = FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The Telecommunication Standardization Sector (IT-T) is a permanent organ of the IT. The IT-T is responsible for studying tech
12、nical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups whic
13、h, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within IT-Ts purview, the necessary standards are prepared on a co
14、llaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPER= RIGHTS The IT draws attention to the possibility that the practice or i
15、mplementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The IT takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by IT members or others outside of the Recommendation development p
16、rocess. As of the date of approval of this Recommendation, the IT had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore s

22、commendation X.722, Information technology - Open Systems Interconnection - Structure of management information: Guidelines for the definition of managed objects. The purpose of the graphic notation is to provide an overview of TMN specifications for TMN specifiers, implementors and users. The graph
23、ic notation provides an overview of what definitions exist and the relationships between these definitions. To accomplish this overview, not all information provided in the templates has to be presented in the graphic notation. Therefore, the graphic notation covers only a subset of the information
24、found in and required by the templates. If inconsistencies between Alphanumeric GDMOIGRM and Graphic GDMO specifications are discovered, the alphanumeric specification is normative. The graphic notation allows both detailed and compact depictions of specifications. The compact notation is expected t
